When Twitter asks `` What are you doing , '' maybe you should be following tweets on job advice .

When microblogging and social networking site Twitter debuted three years ago , plenty of people wrote it off as yet another pointless addition in the overcrowded networking world .

Considering the site only allows people to post , or Tweet , messages of 140 characters or less , you ca n't blame early skeptics .

But little by little , users proved the site 's worth to nonbelievers . Last year , student James Karl Buck was traveling in Egypt and wound up in jail . He Tweeted `` arrested '' to notify his friends of what was going on and ultimately get out of jail .

During the 2008 presidential election , candidates reached out to voters using the service . When a plane crashed into the Hudson River in January , a Twitter user posted the first photograph from the scene .

Although we 're in the nascent stage of Twitter 's existence and therefore have no idea how long it will be around , we do know it has more growing to do .

If you 're not yet certain you want to start posting your own daily activities for everyone to read , you can still use the service as a resource for tips on finding a job and keeping up with industry news . Job seekers can follow people who will make your job search process easier , from the interviewing stage to the salary negotiations .

I follow many people whom I think give great advice , post informative articles and know what they 're talking about . Seeing as the Twitter feed refreshes constantly so that I see new posts instantly , it 's like having a scrolling news ticker about only the subjects I want to read . I suggest you do the same to improve your job search .

Here are the 10 job Tweeters you should be following .
